See Figure 1
The engine and emission control systems utilize a Data Link Connector (DLC) so that a scan tool can communicate with the ECM, thereby reading stored DTC's and freeze frame data for component testing. The DLC used with these engines complies with SAE regulation J1962 in location, shape and terminal identification.
An OBD-II serial data line is used for either the Suzuki scan tool (Tech-1) or a generic scan tool to communicate with the ECM. Only the Suzuki scan tool can be used to communicate with other control modules, such as the airbag module and the ABS control module, etc., in these vehicles.
